Technology for high measurement accuracy and precision

High Definition Signal Transmission and Autocoding

High Definition Signal Transmission

Accuracy and precision of blood glucose measurements result from a combination of various elements. In principle, the glucose molecules in a blood sample are translated into electrons through biochemical substances which can be measured by creating an electric current (other technologies are also common in the market, e. g. photometry). The higher the measured current, the higher the blood glucose value.

However, the current generated from the measurement is extremely low and therefore sensitive to interference. The signal transmission is crucial for the quality of the measurement.1

The concept of the shortest possible signal path has been consistently applied. All unnecessary amounts of conductive distances were eliminated on the test strips, and gold electrodes in the device as well as in every individual test strip ensure optimal signal transmission. Furthermore, gold-plated battery contacts guarantee a stable operating voltage at all times.1

Short signal paths permit interference-free transmission of the signal. Gold is one of the most corrosion-resistant of all established conductive materials, ensuring optimal signal transmission from test strip to measurement device.1

Autocoding

The meter automatically identifies a specific test strip lot code after the insertion of a mylife test strip into mylife Pura X (Autocoding). This Autocoding feature allows the meter to cope with variations in test strip productions in order to ensure a high level of accuracy and precision.

100 % of the test results fall within the accuracy requirements according to ISO 15197:2013

With the IVD standard ISO 15197:20132 the minimal requirements for measurement precision and system accuracy have been defined more demanding. In this more selective context, mylife Pura X’s advanced measuring technique leads to the following results3,4:
